[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a water flow velocity detector, which has the following beneficial effects:

[0020] 1. For this water flow velocity detector, through the settings of the cylinder, servo motor, first round rod, A gear, B gear, second round rod and turbine, the staff places it on the water surface, and then the staff starts the power supply of the servo motor. The servo motor starts to drive the first round rod to rotate. The rotation of the first round rod drives the A gear to rotate. The rotation of the A gear drives the B gear to rotate. The rotation of the B gear causes the second round rod to rotate. The rotation of the second round rod causes the turbine to rotate. The rotation of the turbine causes the device to move, so that the device can move to different positions on the water surface, and thus the device can detect the water flow velocity at different positions on the water surface, thereby reducing the detection error.

[0021] 2. For this water flow velocity detector, through the settings of the concave block, first cylinder, first rotating rod, second cylinder, second rotating rod, third cylinder, floating plate, connecting column and floating buoy, after the device finishes detecting the flow velocity, the staff drags the device back to the shore through the towing rope. Then the staff loosens the first cylinder, second cylinder and third cylinder by rotating the limiting ring. Then the staff rotates the first rotating rod, second rotating rod and floating plate, so that the staff can fold the device, which is convenient for the staff to carry the device. At the same time, when detecting the water flow velocity, the device floats on the water surface through the floating plate and floating buoy, which reduces the staff from holding the device for a long time to detect the water flow velocity, thus improving the convenience of using the device.

The rotation of the turbine 18 enables the device to move, so that the device can move to different positions on the water surface;

[0040] S2: Then, when the device moves to a suitable position, the flowing water causes the speed detector body 25 to detect the water flow velocity. Then, the velocity data is transmitted to the inside of the recorder body 29 to record the water flow velocity;

[0041] S3: Finally, when the device finishes detecting the flow velocity, the staff drags the device back to the shore through the towing rope. Then, the staff loosens the first cylinder 3, the second cylinder 5, and the third cylinder 7 by rotating the limiting ring 19. Then, the staff rotates the first rotating rod 4, the second rotating rod 6, and the floating plate 9, so that the staff can fold the device.
